What is Keyword Cannibalization and How to Fix It?

What Is Keyword Cannibalization?

Keyword cannibalization occurs when a website’s content strategy leads to multiple pages targeting identical or very similar keywords, thereby competing against each other in search engine results pages (SERPs). This internal competition is detrimental to a site’s SEO performance, as search engines struggle to determine the most relevant page to display for a given search query. Instead of consolidating the site’s authority and relevance to a particular topic or keyword, cannibalization disperses it, often resulting in lower rankings for all involved pages. Understanding and addressing keyword cannibalization is crucial for maintaining a focused and effective SEO strategy.

What Are Examples of Keyword Cannibalization?

To illustrate keyword cannibalization, consider a blog dedicated to digital marketing that publishes multiple articles on “social media marketing tips.” If these articles share similar keywords without clear differentiation or targeting, they end up competing with each other in search results. For instance:

  • One article titled “10 Social Media Marketing Tips for Beginners” and another titled “Social Media Marketing Strategies for New Businesses” might target similar keywords.
  • An e-commerce site has separate product pages for very similar items, like “women’s leather boots” and “ladies’ leather boots,” each optimized for nearly identical search terms.
  • A service provider creates multiple landing pages for the same service, targeting the same location-specific keywords, such as “SEO services in New York” and “New York SEO experts.”

These scenarios lead to keyword cannibalization, where the true potential of each page to rank well and attract targeted traffic is undermined by the site’s internal competition.

Why SEO Keyword Cannibalization is Harmful

Search Engines Get Confused

When multiple pages of a website target the same or similar keywords, search engines like Google struggle to identify which page is most relevant for a specific query. This confusion can lead to none of the pages performing as well as they could if they were clearly differentiated. The search engine’s algorithm may fluctuate between pages, leading to inconsistent visibility and rankings in SERPs.

It Weakens Off-Page Optimization

Keyword cannibalization dilutes the efficacy of off-page SEO efforts, such as backlinking. Instead of all external links pointing to a single, authoritative page on a topic, links are spread across multiple pages, weakening the link equity (or “link juice”) of each page. This dispersion of external authority signals makes it harder for any single page to stand out in SERPs based on off-page SEO factors.

Internal Linking Weight Diminishes

Internal linking is a critical component of on-page SEO, helping to establish site architecture and spread link equity throughout a website. However, when multiple pages target the same keywords, the internal linking structure may inadvertently prioritize one page over another or distribute link equity too thinly. This can lead to a reduction in the perceived importance of each page by search engines, further complicating the ranking process and diminishing the overall SEO performance of the website.

Buy Backlinks the Right Way

Users’ Behavior Gets Worse

Keyword cannibalization not only affects search engine algorithms but also negatively impacts user experience. When visitors encounter multiple similar pages on the same website during their search, it can lead to confusion and frustration. Users may find it difficult to locate the most relevant or comprehensive information they are seeking. This redundancy can decrease user engagement, increase bounce rates, and lower the overall perception of the website’s value. When users struggle to differentiate between content that appears to address the same topic repeatedly, they’re less likely to view the site as a credible and authoritative source.

Crawl Budget Gets Wasted

Search engines allocate a crawl budget for each website, which is the number of pages a search engine bot will crawl within a given timeframe. Keyword cannibalization can lead to a significant waste of this crawl budget, as search engine bots spend time crawling multiple pages with overlapping content instead of discovering new, unique content. This inefficiency can prevent important pages from being indexed in a timely manner or at all, especially for large websites with thousands of pages. Efficient use of the crawl budget is crucial for ensuring that all valuable content is accessible and ranked by search engines.

Is Keyword Cannibalization Always Bad?

While keyword cannibalization is generally harmful to SEO efforts, there are instances where targeting similar keywords across different pages may be strategic. For example, when a website targets various stages of the buyer’s journey or addresses topics with slight variations in user intent. In these cases, it’s vital to clearly differentiate each page through unique content and specific keyword targeting to cater to distinct audience segments or search intents. However, such strategies require careful planning and execution to avoid the adverse effects typically associated with keyword cannibalization.

How Do I Find Cannibalized Keywords?

Search Through Your Website

The first step in identifying keyword cannibalization is to conduct a thorough audit of your website. This involves reviewing the content of each page to identify overlapping keywords and topics. Tools like a spreadsheet can be helpful in organizing and tracking keyword usage across your site. Pay special attention to title tags, meta descriptions, headers, and the body content to spot redundancy. This manual review process can be time-consuming but is essential for understanding the extent of keyword overlap and for planning subsequent optimization strategies.

Google-specific Site Search

Using Google’s site search feature can help pinpoint instances of keyword cannibalization. By entering “site:yourwebsite.com keyword” into the Google search bar, you can see all the pages on your website that Google has indexed for a specific keyword. This method provides a quick overview of how often and where certain keywords appear on your site. Pages that rank for the same keywords and appear closely together in these search results may be competing with each other, indicating potential cannibalization issues. This tool is particularly useful for identifying immediate areas of concern that require in-depth analysis and action.

Using External Tools

To efficiently identify keyword cannibalization, leveraging external SEO tools is highly recommended. These tools can automate the detection process, scanning your entire website to find pages that compete for the same keywords. Popular options include SEMrush, Ahrefs, and Moz, which offer features like keyword tracking, site audits, and content analysis. By using these tools, you can quickly pinpoint cannibalized keywords and assess the impact on your site’s SEO performance. They provide actionable insights and recommendations for resolving keyword overlaps, saving time and enhancing your SEO strategy.

How To Fix Keyword Cannibalization

Restructure Your Website

One of the most effective ways to address keyword cannibalization is by restructuring your website. This involves organizing your content in a way that each page serves a unique purpose and targets a distinct keyword or keyword group. Evaluate your site’s architecture and consider merging similar pages, splitting overly broad pages into more focused ones, or reallocating content to align with specific user intents. A well-structured website helps search engines and users alike understand the hierarchy and relevance of your content, improving your site’s overall SEO.

Create New Landing Pages

If your analysis reveals that multiple products or services are competing for the same keywords, consider creating new landing pages. Each page should focus on a unique aspect of your product or service, targeting specific keywords that match the unique selling points or features. This approach not only resolves keyword cannibalization but also improves the user experience by providing targeted information that matches their search intent.

Consolidate Your Content

In cases where multiple pages target the same keyword without a clear distinction in value or intent, consolidating this content into a single, comprehensive page can be highly beneficial. Combining content not only eliminates internal competition but also creates a stronger, more authoritative page that can perform better in search results. Ensure that the consolidated page is optimized for the primary keyword and provides a depth of information that covers the topic thoroughly.

The Ultimate Guide to Technical SEO

Find New Keywords

Sometimes, the solution to keyword cannibalization lies in identifying new, more specific keywords to target. Conduct keyword research to discover alternative or long-tail keywords that can differentiate similar pages. By targeting these new keywords, you can minimize competition between pages while still attracting relevant traffic. This approach requires a deep understanding of your audience’s search behavior and preferences.

Use 301 Redirects

When consolidating content or eliminating redundant pages, 301 redirects are a crucial tool. They inform search engines that a page has been permanently moved, transferring the link equity to the new or consolidated page. This ensures that any external links pointing to the old pages contribute to the authority of the updated content. Use 301 redirects judiciously to maintain a clean, efficient site structure and to consolidate ranking power where it will have the most impact.

Tips to Prevent Keyword Cannibalization

Create a Targeted Keyword Strategy

Developing a targeted keyword strategy is foundational to preventing keyword cannibalization. This involves conducting thorough keyword research to identify the best keywords for your business and assigning specific keywords to individual pages. Ensure that each page targets a unique set of keywords that reflect the page’s content and purpose. This approach minimizes internal competition and strengthens your website’s topic relevance, making it easier for search engines to understand and rank your content.

Track Keyword Rankings and Performance

Regularly monitoring your keyword rankings and overall performance is essential. Use SEO tools to track how your pages rank for their target keywords over time. Analyzing this data helps you identify potential cannibalization issues early on, as well as opportunities for optimization. If you notice multiple pages fluctuating in rank for the same keyword, it may be a sign of cannibalization that needs to be addressed.

User-generated content (UGC)

Focus on Topics First, Keywords Come Second

Shifting your content strategy to focus on topics rather than individual keywords can help prevent cannibalization. Create content that addresses a topic comprehensively, using a variety of related keywords naturally throughout. This topic cluster model helps establish your site as an authority on a subject, improving your search visibility and minimizing the risk of keyword overlap.

Do Regular Content Audits

Performing regular content audits is crucial for identifying and fixing keyword cannibalization. Audit your website’s content to assess its relevance, performance, and keyword alignment. Look for opportunities to consolidate similar content, eliminate outdated pages, or update pages to target new, more relevant keywords. Regular audits ensure your content remains focused, relevant, and competitive.

Create Comprehensive Pages

Instead of creating multiple pages for closely related keywords, consider developing comprehensive pages that cover a topic in depth. These pillar pages should provide a thorough overview of a topic, incorporating a range of related keywords naturally. Comprehensive pages reduce the need for multiple similar pages, lowering the risk of cannibalization and enhancing the user experience.


Keyword cannibalization is a common issue that can undermine your SEO efforts, but it’s also preventable and fixable. By implementing a strategic approach to content creation, focusing on topics, regularly auditing your content, and carefully planning your keyword strategy, you can avoid the pitfalls of keyword cannibalization. Remember, the goal is to make it as easy as possible for search engines to understand and rank your content, while providing a valuable and relevant experience for your users. Adopting these practices will not only help you prevent keyword cannibalization but also improve your overall SEO performance, driving more targeted traffic to your website.
